The Osight SE MOS is the first and only enclosed emitter red dot optic that mounts directly to the Glock MOS footprint without the need for an additional adaptor plate! A breakthrough design that has a lot more under the hood than just a new way of mounting to the slide, the Osight SE MOS also includes a side-mounting battery with over 85,000 hours of run time, 10 total brightness settings, and multi-reticle options to choose from: circle-dot, circle, or dot.

But the Osight SE MOS doesn’t stop there. The fully enclosed emitter design protects from dust, water, and debris. Motion sensing technology preserves battery life by powering down after 3 minutes and instantly powering back up on movement. The SE MOS also comes with a low-power indication to let the user know when it’s time to change the battery.

Red dots are outstanding sighting systems, but irons are still nice to have. The SE MOS has a lower deck height to provide a perfect co-witness with standard factory irons.

Osight has a range of optics now available; the SE MOS combines proven technology and features with a totally new mounting system to deliver an outstanding red dot on Glock’s most popular optic system. And it’s the only one that does so with an enclosed emitter.

Enclosed emitters are more protected, last longer, and are better for duty, tactical, and carry use. Open emitters can be blocked by rain, snow, or dirt when you need the optic most. Enclosed emitters eliminate this hazard.

Combined with the other great features found in Osight optics, the SE MOS is a lot going for it and does so at a great price. Multi-reticle, motion-activated, long-lasting battery, low-deck height, low power indication, side-loading battery, aspherical lens, and made from 7075-T6 Aluminum.
